Vibecoding turned open-source software projects into a spam attack vector.

Before that you could expect high quality projects from a huge percentage of all apps, so acting on a message like "hey, I made this app, please try" was often a good use of your time.

These days there are at least 10x more of such apps, so assuming rationality the default reaction to "hey, I made this app, please try" will eventually become to not even look, or people will only look at apps from well-known creators.

Considering this it might be that rather than "democratizing" the creation of software vibecoding made it harder for a newcomer without reputation or reach to get their app in front of the eyes of others.
